I don't think a truly complete page exists, but these links are pretty
complete in toto:

In a nutshell: you maintain a high level of nutrients by dosing up to 3-4x a
week(depending on light intensity/plant biomass). Large weekly water changes
(50%) prevent anything from becoming to high. 

It can get pretty technical, but you can begin good Barr page like this one:
http://rubick.com:8002/aquarium/fertilization and do a bit of trial and
error. (At the moment I am not dosing any K2PO4.)

Using the nutrients listed: it's cheap, requires only testing for CO2, uses
basic aquarium maintenance skills to deal with plant health.

In summary: http://www.aquatic-plants.org/fert/est_index/est_index2.html

Not too much technical detail here, but a good summary of the thinking
behind the method:
